"Absolutely," the star of the upcoming thriller told E! News last night at the DGA Theatre in Los Angeles when asked if he's ever afraid of oversharing. "On Twitter I don't share anything personal. I try to keep as much of my personal life to myself, and I don't feel the need to go out and show the world what's happening in my life every second."

Since joining the social networking site June 5, Hemsworth has tweeted 40 times, using the page to post updates for his fans and promote his upcoming projects.

And instead of moody musings or abtastic pics, Liam said he intends to keep his feed work-focused.

"I think it's a good chance to connect with fans in a different way and give fans an inside look on films that you do," Miley's man explained. "But it's very new to me and it scares the hell out of me."
